It is possible that a foreign object (a paper clip, a rubber band or a piece of paper or a coin) has accidentally entered the machine. This can happen at any time, even if your device is new or has been in use for several years.

Check the device for a foreign object. Usually it is a coin that gets stuck to the powerful magnet located inside the device:

When you have identified the foreign object, push the two carriers and pull the hopper in your direction. You will need a second person for this operation. One person closes the carrier and the other pulls the white hopper towards him-/herself

After the hopper is removed, the object is released from the magnet.
